CHARLES P. ZINSER, OF "WASHINGTON, ILLINOIS.

DRAFT CONNECTION FOR EARTH-STIRRING, IMPLEMENTS.

Applieation med october 29, 191.9.

To all whom t may concern:

Be' it known that I, CHARLES P. ZINSER, a citizen of the United States,residing at lVashington, in t-he county of Tazewell and State of-Illinois, have invented 'certain new and useful Improvements inDraft'Connections for Earth-StirringImplements; and l do hereby declarethat the following is a full, clear, and eXact description of theinvention, which will enable others skilled in the art to whichitappertains to make and use the same.

This invention has reference to a draft connection for earth-stirringimplements. It relates more particularly to a draft connection betweenartractor and .a series of two or more cultivators, together withmechanism for positioning the cultivator, or other implement, withrespectl to the said draft connection and the-particular line to befollowed. p

The lmain object of my invention is the provision of a draft devicerigidly secured tofthe rear ofa tractor by means of which a Vseries ofearthstirring implements, such' as cultivators, may be-at'tached so thatall may work.' as a unit to the end that 'a large territory-may bercovered in one operation.y

. Another object is the provision of mechanism of such/a nature that anoperator may adjust the implement, especially if aculti vator,withjrespect to thedraft device, and with respect to the row of plantsbeing cul'- tivated.

A still further object is that 'of providing a draft device forattachment toa powerv machine such as a tractor, for connection theretoof a series of implements, said device being removable in order topermit the tractor tobe used for otherpurposes and in order that theattachment will not be in the way.

' a series ofcultivators drawn thereby.

F ig. 2 is a side elevation of the same.

l is indicative of a tractor of' any desired v behind it ftheyimplements for plowing, cultivating or harrowing. 2 is a yoke securedto some portion of the trac-V tor framing or body, as sometimesprovided, 3 is a draft bar of any suitable ordesired form, to which isattached forwardlyithereof a suitable member such yas ayoke 4, forexample, .connected in any suitable manner to the described yoke 2.y

Attached to each'1 end of ithe draft :bar 3,

which may eXtend'as far asdeSired each-` side of the tractor,.is oneend'of a draft' bar 5, whose other lend is attached forwardly to somesuitable portion of the Aframe or body* of said tractor. y

The connections thus ,".described serve to firmly andrigdly attachsaiddraft' bar, but other and additional bracingmeans maybe employedVifdesired(V The bar '3` and its parts canbe detached of course atanytime it is desired to .use "the tractor for other purposes thanthatfof field work.

6, 7 and 8 indicate the tongues of, in this case, a series of threeindependent cultivators 9, l0 andfll, respectively, to be drawn behindthe said draft Vbar 3..

In practice the tractor in its forward movement kcannot the implementsin the rear each in its proper relation to the row to be cultivated.`Conse-V quently, it is my design and ypurpose to provide means foradjusting the tongues 6, 7 and 8 with respect to the draft-bar sol thateach implement can be independently brought to its required properposition to properly cultivate the row of plants corresponding thereto.

This object may be accomplished vin various ways, I having shown methodsfor so doing.

These different methods are illustrated in Figs. 3, 4: and 5, that insaid FigB first receiving attention herein. f

First, however, the support for the implement tongue may be described asapplicable to all three forms. y I

12 is a supporting brace or stirrupsecured to the under side of theV'tonguev whose lower extremity is `designed to restupon the draft'-bar, spacing the tongue rabove there'b'eing cultivating or j other wellbe directedto drawas examples Athree interposed between the stirrup andthe draft-bar a frame 13 inclosing the latter' and carrying rollers lilto engage the front and rear faces of said bar, the stirrup beingpivoted to said frame by means of la bolt 15, for example.

Now, extending from one side of the frame 13 is an ear 16 to which ispivoted one end of a rod 17 whose other end has pivoted connection witha lever 13 mounted on the draft-bar near the seat of the operator of thetractor, there being a notched sector 19 to which the lever is pivoted,the latter having any usual latch mechanism 20. This structureit isobserved is provided for each of the tongues 6, 7 and 3 or as many moreas it may be the desire or ability to accommodate. n vthis connection itis observed that the middle tongue 7 of the three shown is ofconsiderable length in order that the middle vcultivator in traversingits row will have a position behind the others where it will have spaceto operate. And in order, also, that its tongue in the side movementthereof may not interfere with the wheels of the other two implements itis arched, as shown in Fig. 2, to bring it above said wheels.

ln the second method of swinging the tongue the frame 13', Fig. 4,corresponding to 13, has the ends of a cable 21 attached thereto, eachthen passing around a pulley 22 on the reach, one at each side of thesaid frame 13 as shown, the said cable thence taking several turnsaround and fastened te a drum 23 mounted on the implement. 24; indicatesa hand wheel by which the drum may be turned one way or the otherwhereby to shift the tongue relatively to the draftbar as in the otherinstance.

Fig. 5, which illustrates the third method, is not greatly unlike theone just described. Upon the tongue is mounted a shaft 25 extending tonear the seat of the operator of the implement and having a drum 26 uponwhich a cable 27 is wrapped which takes around opposite pulleys 23corresponding to pulley 22 of Fig. 1, thence having connection with theframe 132.

The last two described forms permit the operator of any given implementto control the direction of travel of his implement whereas in the firstform, Fig. 3, an operator on the tractor is enabled to control theseveral implements from that point.

The rigidly mounted draft-bar of considerable length, it is now clear,serves as a connection for a series of implements whereby a considerableterritory may be gone over in one operation, whether cultivating orharrowing.

1n this connection it is observed that the draftbar is connected to Vthetractor at widely spaced positions. r1`hat is to say, the forward endsof the members 5 where they connect to the machine are widely spacedfrom the point of connection of the draftbar with the yoke 2, and sincethe members are rigid throughout they assist in holding the bar fromteetering and prevent any tendency to a see-sawing motion when the draftupon the bar may vary when, for eX- ample, the cultivator shovels of oneof the outer implements may be out of the ground while the others are inaction. Furthermore, when cultivating, although the tracto r may notmaintain a straight line of travel the implements may be kept closely upto their work so as to produce the best possible cultivation.

Although some such methods as are described herein are preferred for theguiding of the implement, others may be used, keeping in mind the factthat in turning around in the field the mechanism used for the steeringmust be such that it will not interfere with or itself be disarranged asthe tongue swings to wide limits, and for this reason the drums 23, 26are preferably left free to rotate at such times by the pull of thecables thereon.

l claim:

1. 1n a draft rigging, in combination with a tractor, a single draft-barfor attachment thereto of a series of earth stirring implements, saidbar having rigid attachment to the said tractor and supported entirelythereby, and a member at each end of the draftbar connected at one endthereto, and con nected each at its other end to the tractor forward ofthe place of attachment of said bar, all of the parts being rigid withrespect to one another and with respect to the tractor.

2. ln combination with a tractor, a part secured thereto, a draft-barattached substantially at the middle of its length to said part, saiddraft-bar having a length to admit of the attachment of a series ofcultivators thereto, and a member attached to each end of the draft-barand each also attached to the tractor in rigid manner, the said part andsaid members securing the said draft-bar `in of the tractor.

3. 1n combination with a traction engine, a draft attachment thereforincluding a fixed relation to the framesingle rigid bar rigidly attachedto said 'single rigid bar rigidly attached to said engine perpendicularto the line of draft, means for independently connecting each cf aseries of cultivators to said bar to be drawn behind the same, eachhaving its tongue supported by said bar, and-a separate manuallyoperated device operatively engaging each tongue and said bar arrangedwhereby when one of the devices is operated the tongue correspondingthereto will be moved laterally7 with respect to the said bar.

5. In combination with a tractor having a member at its rear lyingperpendicular to its line of draft7 and an implement including a tongueextending forwardly therefrom, a guide movable along the member uponwhich the tongue is supported in pivotal manner, a take-up devicemounted upon the tongue above the member, and mechanism connected to thedevice and the guide at opposite sides thereof operatively connected tothe member at opposite sides of the guide and spaced therefrom.
